To all whom it may concern.

Be it known that I, JAMES A, BRoeAN, a citizen of the United States,residing at Lawrence, in the county of Tjlssex and State ofMassachusetts, have invented certain improvements chines, of which: thefollowing description,

in connection with the accompanying draw ings, is a specification, likereference characters on the drawings indicating like parts in theseveral figures.

This invention relates to fastening insert ing machines, and an objectof the'invention is to improve machines of to sever nails from a'nailstring and drive them into the work. i

A further object ofthe invention is to provide a machine for insertingstring nails which will be adpated to operate on-a nail stringcomposedof relatively soft stock, for example, iron or brass wire, and to thisend an important feature of the invent-ion resides in the provision in astring nailing machine, of mechanism for severing'the nails from thenail string and presenting them to the driver of the machine,constructed and arranged to form oppositely beveled surfaces onthe'points on the nails,thus enabling them to be driven straight intothe work and'also facilitating the proper clinching of the nails. H

The illustrated machine is of the type comprising a fastening receivingmember having a passage to receive the endmost string guide nail or anail string and a nail having a guideway for the nail stringand movablerelatively to the fastening receiv-' ingmember to alzine the guidewaywith the passage of the fastening receiving member to enable the nailsto be anda further feature of the inventionresides in the provision insuch a machine means independent oithe nail string guide and the meansby which the nails are fed for severing the nails from thenailstringfafter theyhave been introduced into the fasteningv receivingmember.

Other objects and features of the invention will appear as thedescriptionproceeds and will be pointed out in' the appended claims.

The illustrated machine comprises a column'2, upon which rests asuperstructure i, on the front of which is supported a head mounted onashaft 8 j ournaled in the superstructure 1-. The swinging'head 9 areviews similar to Fig.- the part-s as. they appear at the cycle ofoperations of the 6 is maintained against the front of the 85superstructure e by castings 10. Slidably mountedin the swinginghead 6are a driver bar 12' carrying a driver 14 and anawl'bar 16 carrying anawl 18. The driver bar12 is raised by a cam on the shaft8 operating.

on the bar, and-is de pressed to drive the nails by. a spring 21 coiledabout apart on the superstructure 4,.

The awlbar 16 i's-provided with:teeth 23 with which mesh the teeth of a,se ment-gear 22 fixed to a shaft 2 i'journaled in the super structure 4.An arm 26 on the shaft 24 carrise a roll 28 riding in a cam groove 30 ina cam .32 on the shaft 8." Theby means including a block' 33 adjustablein.

a groove-in the head'G, as clearly appearsfrom Fig. 1., On the-lowerendof the head 6 1s a fastening receiving member in the form ofa' throatSthaving substantially ver-" 105 tical passages 36 and '38 operatingconnections 6O a view on an enlarged scale of "70 guides id to theguideways as in the driver 1d and the awl 18 respectively reciprocate.The nails to be driven are successively introduced. into the passage 36when the driver is elevated out of the passage. Preferably, and asshown, the nails are controlled. during their movement through thethroat passage 36 by a spring pressed finger 39 pivoted in the throat3a.

The nail string is supplied to the machine on a reel 40 supported on thesuperstructure 4t by a bracket 4-2. The nail string is wound on the reel4.0 and the reel is applied to the machine in such a manner that in theoperation of the machine the nail string will be unwound from the top ofthe reel with the nail in the string arranged points down and with theirheads disposed outwardly from the string, or to the left, as seen inFig. 1. The nail string, as it is drawn from the reel passes through aguiding tube as mounted on the bracket 4&2, and the end of the string isintroduced into a guideway d6 formed in a nail string guide 46. Asshown, the guide 4-8 is formed with two guideways 46 to enable two nailstrings of different characters to be supplied to the machine, and thenail strings are retained in the guideways by leaf springs 50 secured tothe guide 48 by set screws or the like When two nail strings aresupplied to the machine the reel 40 and guide as: are duplicated. Thenail string guide lS is carried by a shaft 54: fulcrumed in the head 6of the niachine. In order to oscillate the guide t8, the shaft 54. isprovided with 211131111 carrying a cainroll 58 disposed to ride on theperiphery of the cam The cam roll of the arm 56 is maintained againstthe eriphery of the cam 32 by a spring 60. he shaft 54% is mounted "forendwise movement in the head 4- to the end that the nails in theguideways 4E6 oi": the guide 48 may be selectively presented to thepassage 36 of the throat 34. lhe endwise movement of machine bymechanism including a hand. lever 62 appearing at the righthand side ofthe machine, as seen in 1. The mechanism thus far described constitutesby itself no part of the present invention and is clearly disclosed inUnited States Letters Patent No. l,el0l,2"z',-,granted Dec. 27, 1921, onan application of George Goddu and Fred L. Mackenzie. A more completedescription of such mechanism is accordingly deemed .unnecessary.

The nail strings on their way from the guide a8 pass through asupplementary guide 6% carried by a strip 66 pivoted at 68 on themachine frame and having an upwardly extending portion '70 normallyengaging a lugf? 1 on the casting 10. i

he nail string is intermittently ted to the shaft 54: is efi'ected inthe illustrated,

place on the guide by a plate introduce the endniost nail of the nailstring successively into the passage 36 or the throat 3% by meansincluding a blade 72 mounted in a holder 7a, in which it may be adjustedby a screw or the like 76. A set screw 78 on the side of the holderTelserves to secure the blade 72 in adjusted position in the holder. Inthe present instance of the invention, the holder 74 is carried by anarm 80 mounted on a shaft 82, upon which is coiled a. spring 8% tendingnormall to press the blade '72 against the opposite surface of the nailstring guide 18. A cam roll. 66 on the lower end of the arm is disposedto ride on a cam surface 88 on the rear edge of the laterally extendingportion 90 of the nail string guide 4:8. The cam surface 88 accordinglycontrols the blade 72 in its po-- sition with respect to the nail stringguide Theshatt 82 is sleeved into the end of an arm 92 pivoted looselyon a shaft 94 journaled in the head .6 or" the machine. As shown, thearm 92 is extended rearwardly from the shaft 9d and is formed with abowed portion 96, which terminates in an upwardly extending bar 98channeled to receive a sliding block 100, to which is pivoted a lever.102 having a cainv roll 10% at its upper end riding in the cam groove30 of the cam T is cam through the operating connections above describedreciprocates the blade 72 in a substantially verti= cal direction alongthe side of the nail string guide 918.

The illustrated machine is particularly designed to operate on nailstrings of relatirely soft material, such a nail string being shown inFig. 2 and consisting of a wire bent or folded upon itself at intervalsas indicated at A to constitute the heads of the nails in the string andhaving portions cut away at B to assist in torrning points on the shanksof the nails. The wire may be made of iron or brass, for instance, butis preferably soft enough to enable it to be cut or bent readily. inaccordance with the invention, n'ieans is provided for severing theendrnost nail from the 'nail string after it has been iied into thepassage 36 ofthe throat 34E of a character to cause the nails topenetrate the worlt. easily, so that they will not buckle wnen they aredriven, and to be otherwise properly inserted into the worlr. As shown,such means comprises die plate 106 recessed into the lower end of thenail string guide 48 and maintained in headed pin or the like 108. Thecutting edge 110 of the die 106 formed at the intersection of its lowersurface 112 and the surface contiguous to the path of nioven'ient of thenail string. 'l he die plate 106 is so disposed with relation totheupper surface of the throat Se that when the endmost nail of the nail.

be spaced inwardly from the inner surfaces guideways 46 of the nailstring 116 of the I guide 18. Consequently; the point of the secondnailin the string is presented to the cutting edge of the die plate 106 atan angleto the contiguous surface 114 of-the plate. As shown; theinclination of the surface 11% to the shank of the nailis' increasedadjacent to the edge 110,.as indicated at 118,].

but it is obtained apparent that'like results may-be by continuing thesurface 114 at the same an le to the shank of the nail as atthe portion118. Y

in the present instance of the invention,

the nail string severing means further coinprises a cutter having itsedge disposed to abut substantially against the edge 110 of the dieplate 106; and' wardly and upwardly from its edge, thus presenting abeveled surface "opposite the portion 118 of the surface 114 of the dieplate 110. 'lVith thisconstruction, whenthecutter 1 0 is operated tosever the endmost nail from the nail 1100f the die plate surfaces areformed on the point of the second nail by the neveledend of the cutter120 and the inclined surface 114 of the die platev 106, thus enablingthe. nail to be easily ins serted into the work and hyreason "of thefact that the point of ,the'n'ail is about equallyv beveled on ea 11side, practically insuring that the nail will be driven straight Inmaking the nail string,"

into the work. the wire is preferably cutinore'than half the way throughat the v points of the nails when theya're-severed from the nail stringby the nailing machine are also reduced on their sides intermediatebetween the beveled surfaces formed bv the,

cutter'120 and the die plate lOG. In this way, a point is formed on thenails which-not only enables them to be driven straight but which mayalso be perfectly clinched. The cutter 120 is dovetailed into the splitlower end of a holder 122, as shown in h1g1 8, and

may be maintained in any desired position of ad ustment in the holder122 by a headed screw 124. Preferably, and asshown a post 125 is formedon the holder 122'in positionv to abut against the opposed surface ofthe nail string giude a8 in order to facilitate the setting of the'blade120 in the holder. ,The holder 122 is pivoted on the nailstring guide48-h means of'apin 126 extendinmiaterall froin'the nail string guide andpassing I through the forked upper en'dof the holder.
